Probably because they weren't too successful. I personally think Lisp
is super-cool, but inappropriate for space (or any reliability-
sensitive work).
If I remember correctly, when they used Lisp in the probe, there was a
bug and they used Lisp's live patching and interactive debugging to
fix it, so they only missed their target by a quadrillion miles
instead of missing it by a gazillion miles.
On the other hand, the bug wouldn't have happened in the first place,
if they used a good static language. I'll let someone who knows better
fill in the details (that's why I added comp.lang.lisp to the groups)
Happy space exploration and exploitation!
